Answer:
D
Step-by-step explanation:
First you need to find which function represents f(g(x)) and then you replace each x in this new function by 2.
f(4), for example, is f when x = 4, right? So f(4) = -4+4 = 0
So, f(g(x)) will represent f when x = g(x). x = g(x) when x = -2x-3
So, f(g(x)) = f(-2x-3) = -(-2x-3) + 4
= -(-2x)-(-3)+4
= 2x + 3 + 4
= 2x + 7
So f(g(x)) = 2x + 7.
Now when x = 2, f(g(x)) = 2*2 + 4 = 11, which is option D.
